There were 26 pairs of little terns recorded on Foulney Island

Sarah Dalrymple, from the trust, said: "It's been a fantastic season for the terns.

"These delicate white seabirds are incredible. Arctic terns migrate from Antarctica to the UK each year to breed, while little terns are our second rarest seabird.

"They're very vulnerable to predation, disturbance and weather, so for them to do so well in 2017 is brilliant news for all three species of tern."

Dave Blackledge, from RSPB Hodbarrow, said: "Staff and volunteers from both organisations have worked around the clock to protect these terns, so it is massive thanks to their dedicated efforts that these elegant seabirds have done so well."
